There's no "best" - this is subjective.

You have a list of apps, and you can choose whether or not to allow an app access to the Internet over WiFi or Mobile data.

Whether or not you want to let an app access the Internet is up to you.

Is it (technically) possible to add "on-demand" feature ?
Maybe something close to how LBE works ... Yes/No/Don't ask again
Suggestion...

Not on a granular, per-app basis, at least right now.

NetGuard for Android works by creating a VPN service at system level. Based on your choices in the allow/deny screen, NetGuard will set up VPN rules for which apps are forced through the "VPN". The "VPN" isn't a real VPN; rather, it just sinkholes the traffic to nowhere.

The limitation here is that when creating these rules, we can only set which applications' traffic enters the VPN. We can't granularly control which requests or hosts they can talk to, on a per-app basis. It would be possible to set "for all apps" a whitelist/blacklist of IP addresses, but this would be quite different, and would likely be less useful as a firewall, and more useful as simply an "ad blocker".

The VPN interface doesn't tell us which app is trying to access the internet though - we need to set it up before-hand. There are ways to tell, but Google (or a careful OEM) could easily block those with SELinux policy updates, and the goal here is to try to get all the functionality we need without any kind of root access.

Nice app for non rooted users.
I've just created an issue on Github though.

French translation done.

I'll try to create an icon this weekend if I have free time. Let me know if you want a specific color,... etc.

The problem you have reported is probably caused by a broken VPN implementation in your ROM. I will look into it later this week more detailed.

I like to keep the current colors, realizing not everybody will like them, but I know from experience I can't make everybody happy anyway.

Thanks for your translation!
